摘要： 通过对广花盆地塌陷灾害调查，分析了广花盆地地面塌陷类型、时空分布特征、影响因素、形成机理.结果表明：本地区地面塌陷主要为隐伏岩溶地面塌陷.岩溶的发育程度、上覆松散岩土层是岩溶地面塌陷形成的基本条件；强烈地下水位变动、振动（震动）荷载等动力扰动是岩溶地面塌陷的动力条件.根据广花盆地地面塌陷的成因特点, 提出了通过控制水位变化幅度、减少对土体扰动等预防措施，本研究可为本地区的城市建设提供参考.

Abstract: Based on the investigation of ground collapse in the Guanghua basin, it analyzes the types of ground collapse, spatiotemporal distributing characteristics, control factors and the formation mechanism of karst collapse. The results show that the ground collapse is mainly concealed karst collapse in carbonate rock distribution area, and that the development degree of karst and the overlying loose rock soil mass are the basic formation conditionssubstantial changes in groundwater table and vibration load are the induced dynamic formation conditions of the karst collapse. Regarding the genetic characteristics of ground collapse, some preventive measures, such as controlling underground water level variation and reducing the disturbance of soil, are proposed. The study provides good reference for city construction in the Guanghua basin.

Key words: Guanghua basin; karst collapse；spatiotemporal distributing characteristics; formation mechanism; preventive measures
